TESTING/EIG/zget35.f(3)

NAME
TESTING/EIG/zget35.f

SYNOPSIS

  Functions/Subroutines
subroutine zget35 (rmax, lmax, ninfo, knt, nin)
ZGET35

Function/Subroutine Documentation

  subroutine zget35 (double precision rmax, integer lmax, integer ninfo, integer knt, integer nin)

ZGET35

Purpose:

    !>
    !> ZGET35 tests ZTRSYL, a routine for solving the Sylvester matrix
    !> equation
    !>
    !>    op(A)*X + ISGN*X*op(B) = scale*C,
    !>
    !> A and B are assumed to be in Schur canonical form, op() represents an
    !> optional transpose, and ISGN can be -1 or +1.  Scale is an output
    !> less than or equal to 1, chosen to avoid overflow in X.
    !>
    !> The test code verifies that the following residual is order 1:
    !>
    !>    norm(op(A)*X + ISGN*X*op(B) - scale*C) /
    !>        (EPS*max(norm(A),norm(B))*norm(X))
    !>

Parameters
    RMAX

    !>          RMAX is DOUBLE PRECISION
    !>          Value of the largest test ratio.
    !>

    LMAX

    !>          LMAX is INTEGER
    !>          Example number where largest test ratio achieved.
    !>

    NINFO

    !>          NINFO is INTEGER
    !>          Number of examples where INFO is nonzero.
    !>

    KNT

    !>          KNT is INTEGER
    !>          Total number of examples tested.
    !>

    NIN

    !>          NIN is INTEGER
    !>          Input logical unit number.
